TL;DR
Argentina runs on QR and bank transfers (alias/CBU/CVU), not cash. As a foreigner without a DNI you can still go cashless: pay any QR and send pesos to any alias straight from a USD balance with CacaoCash, no DNI, no local account, at the crypto dollar rate. Keep a little cash only for tiny vendors and tips.
Argentina might be the easiest country in Latin America to travel without carrying cash, if you know how locals actually pay. Day to day, Argentines barely use bills. They pay by scanning QR codes and by sending instant bank transfers to an alias, CVU, or CBU. As a foreigner without a DNI you can do almost exactly the same, and skip the ATM lines, the cueva runs, and the security risk of walking around with a wad of pesos.
This guide is for tourists, digital nomads, and expats who want to spend in pesos without handling cash. The short version: pay merchants by QR, send people pesos by transfer, and fund both from a USD balance at the crypto dollar rate with CacaoCash, no DNI or local bank required.
QR is the default way to pay a business in Argentina. You open the app, scan the merchant's Mercado Pago, MODO, or bank QR, type the amount if needed, and confirm. With CacaoCash the pesos come from your USD balance at the crypto dollar rate, no DNI and no Argentine account. Full walkthrough: how to pay QR codes in Argentina without a DNI, including paying Mercado Pago as a foreigner.
For anything that is not a merchant QR, rent, a friend, a landlord, a freelancer, splitting a dinner, you send a peso transfer to their alias, CVU, or CBU. When someone says pasame tu alias, this is what they mean. You can send to any of them straight from your dollars: how to send pesos to an alias, CBU or CVU. Paying for a place to stay?

Not sure what an alias, CVU or CBU even is? Start with CBU, CVU and alias explained.
Cashless covers the vast majority of spending, but keep a small amount of pesos for the edges: some tiny kioscos, ferias and craft markets, rural areas, tips in cash, and the occasional taxi that only takes bills. A modest cushion handles these; you do not need to fund your whole trip in cash.
CacaoCash is a USD wallet for foreigners in Argentina. You hold dollars, and when you pay it converts to pesos at the crypto dollar rate, the favorable side of the roughly 10 percent gap a foreign card charges. You can pay any QR and send to any alias, CVU or CBU, all without a DNI or local bank account. For every payment method, see the Argentina payments cheat sheet.
Almost entirely. QR and transfers cover shops, restaurants, transport and rent. Keep a small amount of pesos for tiny vendors, markets and tips.
No. With CacaoCash you pay QR and send to any alias, CVU or CBU using only a foreign passport, no DNI and no Argentine bank account.
Usually yes. A foreign card converts at the non-resident rate; paying pesos at the crypto dollar rate is around 10 percent more pesos per dollar, on every purchase.
